Excuse me if this request is in the wrong place:

I have added a working custom date field to my activity page by editing the post-form.php and the the bp-custom.php. This is in my bp-custom.php:

// CUSTOM DATE FIELD
function add_date_to_activity( $content, $user_id, $activity_id ) {
bp_activity_update_meta( $activity_id,'thedate', $_POST['thedate'] );
}
add_action( 'bp_activity_posted_update', 'add_date_to_activity', 10, 3 );
function my_datemeta() {
$my_datemeta = bp_activity_get_meta( bp_get_activity_id(),'thedate' );
if (is_user_logged_in()) : {
echo "<span class='datefont'>" . $my_datemeta . "</span></br>";
}
endif;
}
add_action( 'bp_activity_entry_meta','my_datemeta' );

Now I am trying to sort the posted activities by this date field instead of the standard sort by activity-id’s. Is there any way to override the standard sort function?

Thanks in advance, i’d be happy to share more information if necessary
